Why not? The church is an organization, too, and thus has processes working toward some goal.
This is what Paul Brantley, the new director of the Seventh-day Adventist Church, wants. He aims to make his church to be the world’s best-run organization, To do that, he’s looking at some form of assessment to help him achieve his goals.

Six Sigma or any other continuous improvement methodologies will definitely do good for any organization.
We wish Paul Brantley good luck. Just by considering improvement and assessment, already he’s on the right track.
